Title: Molecular turbo-pump
Inventor: OKAWADA TAKESHI
IPC: F04D19/04
Filed: 1981-05-22
Abstract: PURPOSE:To increase the compression ratio of a molecular turbo-pump, by shaping the profile of rotor and stator blades in a triangular form having a large thickness at its middle portion but a small thickness at its suction and discharge sides, and arranging the blades such that the rotor blades are convex in the direction of their rotation but the stator blades are convex in the opposite direction. CONSTITUTION:The blade profile of rotors 2 and stators 6 are shaped in a triangular form having a large thickness at its middle portion but a small thickness at its suction and discharge sides. Further, these rotors 2 and stators 6 are arranged such that the rotors 2 are convex in the direction of their rotation but the stators 6 are convex in the opposite direction to rotation of the rotors 2. By employing such an arrangement of blades and a blade profile, probability of molecules of gas to pass from the suction side to the discharge side of the blades is increased and at the same time the maximum compression ratio is increased since the inlet area is made greater as compared with an arrangement employing a flat cascade as shown by the broken line in the drawing. Resultantly, it is enabled to reduce the number of stages and to obtain a molecular turbo-pump inexpensively but having a high performance.

Title: Avalanche photo diode
IPC: H01L31/107
Filed: 1992-03-31
Abstract: PURPOSE:To augment the rapidity and sensitivity of the title avalanche photo diode(APD) by a method wherein the carrier concentration, etc., is adjusted so that the third layer 3 may be depleted at least in the actuation state of APD. CONSTITUTION:The third layer 3 is designed to be depleted at least in the actuation state of the title APD so that the film thickness of depletion layer to decide the element capacity may be the total film thickness of the layers 1, 2, 3 thereby becoming thicker by the thickness of the layer 3 than the conventional film thickness. Next, the electrons generated by photo-absorption are drifted by an electric field to produce new electron hole couples (a) in a doubling layer 2 and then these electron hole couples run away in inverse direction to repeat the production (b), (c) of new electron hole couples in the doubling layer 2 for gaining in APD. During these procedures, the time for the hole to run through the depletion layer is to be t3 while the times for the electrons are to be t2, t1 so that t2 may be t3>t2 by adjusting the film thickness of the third layer 3 thereby enabling the element capacity to be reduced without lengthening the response time.

Title: Speed change gear
Inventor: HIROZAWA KOUICHIROU
IPC: F16H37/02
Filed: 1982-05-10
Abstract: PURPOSE:To reduce wear of a speed change gear at the region of its transmission ratio, by employing such as an arrangement that power is not transmitted by a stepless transmission during the while when power is being transmitted by a step transmission and the step transmission is operated at a transmission ratio near or outside of the end of the stepless speed changing range. CONSTITUTION:A speed change mechanism of this invention consists of a stepless transmission 12, a step transmission the transmission ratio of which is fixed at a value near and/or outside of the end of the change-speed range of the stepless transmission 12, and a selector mechanism for operating either of the avove two transmissions selectively. During the while when power is being transmitted at stages 14, 16 of the step transmission, the stepless transmission 12 is made not to transmit power. Therefore, the transmission ratio at the time is near or outside of the end of the stepless speed changing range. By employing such an arrangement, durability at the region of the transmission ratio where wear is caused most can be increased as compared with the case in which speed is changed only by use of the stepless transmission 12. Further, the range of transmission ratio is also increased since the fixed-step change- speed range is added to the stepless change-speed range.

Filed: 1985-04-11
Abstract: PURPOSE:To simultaneously set the output voltage and the operating point of an overcurrent protecting circuit by applying reference voltages regarding the output voltage of a D/A converter to the first comparator for controlling the output voltage and second comparator for protecting against an overcurrent. CONSTITUTION:An auxiliary power source 10 supplies power to a D/A converter 20 and a controller 30 to control a switching regulator body 40 with a control signal from the controller 30. The converter 20 has a plurality of input terminals 21, and inputs digital signals B1-B8. Constant-voltage circuits J1, J2 which supply constant-currents to the converter 20 are connected with the power source 10. Further, the controller 30 has two comparators to compare the output voltage V0 and the output current I0 with a reference voltage. Thus, when an overcurrent is flowed, the voltage V2 decreases to become V1=V2, an overcurrent protecting circuit is operated. When the output voltage V0 is increased, the voltage V1 is raised, and the overcurrent protecting circuit is operated with a small output current.

Abstract: PURPOSE:To comparatively simply resect even a hard living body tissue and to improve the operability by providing an advance/retreat operation mechanism for executing an advance/retreat operation of a vibration transfer member in its axial direction against an external cover tube on a hand piece part. CONSTITUTION:When a turning ring 15 is turned and operated, a guide pin 18 is moved in the axial direction O of a hand piece part 2 along a cam groove 16 of the ring 15, and an ultrasonic vibrator 3 moves along the axial direction O. In this case, the operation of the guide pin 18 is absorbed in a slot of the hand piece part 2, and in connection with the turning operation of the turning ring 15, the hand piece part 2 does not move along the axial direction O. Accordingly, the ultrasonic vibrator 3 and a vibration transfer member 8 of the inside move integrally along the axial direction O, the vibration transfer member 8 executes an advance/retreat operation in its axial direction against an external cover tube 11 and an inner blade 13 executes an advance/retreat motion in the axial direction of the vibration transfer member 8 against the outer blade 12. According to this constitution, the turning operation force of the turning ring 15 is operated as operation force for a resection work of a living body tissue.

Title: Halftone image processor
Inventor: OKABASHI TOSHIHIRO
IPC: H04N1/40
Filed: 1993-03-10
Abstract: PURPOSE:To improve the gradation expression of print picture quality in a halftone by reducing driving nonuniformity at a printing part in the case of recording an image. CONSTITUTION:Concernng data inputted by an image reader, data quantized by a halftone image processing circuit are successively processed for the unit of two pixels. Concerning these data of two pixels, first of all, whether it is an edge or not is decided by an edge decision part 1. Based on the result of this decision, an objective image for performing arithmetic operation between pixels is switched. When it is not the edge, arithmetic operation is executed by an arithmetic part 2 and when it is the edge, correction emphasis is performed. Thus, even when a dot is moved by driving nonuniformity at the printer part, it does not stand out and picture quality is improved especially concerning the halftone part.

Abstract: PURPOSE:To considerably relieve the load on a host CPU by providing two means being a 1st means inverting bit pattern of a data in one byte and a 2nd means for deciding a preset condition and starting the 1st means only when the preset condition is satisfied. CONSTITUTION:Accessing to an image memory 6 is supposed to be an access to a picture buffer 7 or a code buffer 8, then an address of the accessed image memory is inputted to a temporary address register 10 and fed to a detection circuit 15. The detection circuit 15 detects whether the temporary address is an area of the picture buffer 7 or the area of the code buffer 8. If the address is in an area of the picture buffer 7, a control signal 2 is active and a bit pattern inversion circuit 3 is started. Moreover, if the address is in the area of the code buffer 8, the control signal 2 is made inactive and the bit pattern inversion circuit 3 is not started. The bit pattern inversion circuit 3 does not invert the bit pattern of an input data 4 but outputs an output data 5.
